Chapter 1. Appliance safety precautions

Observe physical, electrical, and electronic component safety precautions.

Physical

Ensure that your equipment rack is placed in a dust-free, well-ventilated area close to an uninterruptible power supply (UPS). Leave enough room behind and around the rack for services and sufficient airflow.

v Keep the area around the appliance clean and free of clutter. v Place the appliance top cover and any appliance components that were removed away from the

appliance or on a table so that they do not accidentally get damaged.

v While you are working on the appliance, do not wear loose clothing such as neckties and unbuttoned

shirt sleeves. They can retain a charge even if you are wearing a wrist strap, or could be pulled into a fan.

v After you access the inside of the appliance, close the appliance and secure it to the rack unit with the

retention screws after you ensure that all connections are made.

v Close the rack’s front door and all panels and components on the appliances when not servicing to

maintain proper cooling.

Electrical

Basic electrical safety precautions must be followed to protect yourself and the appliance:

v Do not work alone with high-voltage components. v Be aware of the locations of the power switch on the appliance and the room’s emergency power-off

switch, disconnection switch, or electrical outlet. If an electrical accident occurs, quickly remove power from the system.

DANGER

A danger of explosion exists if the Onboard battery is installed upside down, which reverses its polarities. This battery must be replaced only with the same or an equivalent type that is recommended by the manufacturer. Dispose of used batteries according to the battery manufacturer’s instructions.

Electronic components

Electrostatic discharge (ESD) is generated by two objects with different electrical charges when they come into contact with each other. An ESD neutralizes this difference, which can damage electronic components and printed circuit boards (PCBs). In general, the following measures are sufficient to neutralize this difference before contact is made to protect equipment from ESD:

v Use a grounded wrist strap that is designed to prevent ESDs. v Keep all components in their antistatic containers until ready for installation. v Touch a grounded metal object before you remove any board from its antistatic container. v Remove any jewelry or metal objects from your body. They are excellent metal conductors that can

create short circuits and harm you if they come into contact with printed circuit boards or areas where power is present.

Chapter 3. Install the appliance into a rack

Many racks are on the market, which means that the assembly procedure might differ slightly. This rail fits a rack between 28.5" and 35.5" deep.

Prepare for installation

Assemble tools

A #2 Phillips screwdriver and a cage nut tool are needed to install and secure the rails to the appliance.

Wear a set of leather work gloves when racking the appliance. They help to get a grip on the appliance and avoid injury from any metal edges.

CAUTION: Do not use of any sort of hammer to secure the rails on the appliance. A hammer might damage the drives within the chassis and possibly void the warranty.

Choose a setup location

Decide on a suitable location for the rack unit that holds your appliance.

Table 5. Appliance location considerations

Factor Comments

Restricted access location Install this appliance in a physically secure, limited access location only, such as a

service closet or data center. Clean environment Situate it in a clean, well-ventilated, dust-free area. Ambient operating temperature If installed in a closed or multi-unit rack assembly, the ambient operating

temperature of the rack environment might be greater than the ambient

temperature of the room. Install the equipment in an environment compatible with

the maximum rated ambient temperature (TMRA) for the appliance. Sufficient airflow Mount the equipment into a rack so that the amount of airflow that is needed for

safe operation is not compromised. Leave enough clearance in front of the rack to

open the front door completely (36 inches). Leave about 36 inches of clearance

behind the rack for sufficient airflow and ease in servicing. Mechanical loading Mount the equipment into a rack so that a hazardous condition does not arise due

to uneven mechanical loading. Install heavier items into the bottom of the

equipment rack to keep the rack stable. Mount equipment in a rack evenly to

prevent a later hazard. Circuit overloading Consideration should be given to the connection of the equipment to the power

supply circuitry and the effect that any possible overloading of circuits might have

on overcurrent protection and power supply wiring. Appropriate consideration of

equipment nameplate ratings should be used when addressing this concern.

Note: The maximum current draw is printed on a label on the appliance power

supplies. The system can draw more than 15 Amps at startup (inrush current). Reliable ground A reliable ground must be maintained always. To ensure grounding, the rack itself

must be grounded. Particular attention should be given to power supply

connections other than the direct connections to the branch circuit, such as the use

of power distribution units.

Table 5. Appliance location considerations (continued)

Factor Comments

Power supply Use a regulating uninterruptible power supply (UPS) to protect the appliance from

power surges and voltage spikes, and to keep your system operating in a power failure.

Heat, electricity, and EMI Avoid areas where heat, electrical noise, and electromagnetic fields are generated.

Prepare the rack

1. Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full

weight of the rack resting on them.

v In single rack installations, attach stabilizers to the rack. v In multiple rack installations, couple the racks together.

2. Check that the rack is stable before extending an appliance from the rack.

3. Extend only one appliance at a time. Extending two or more simultaneously can destabilize the rack.

4. Determine the placement of each appliance in the rack before you install the rails.

5. Install the heaviest appliances (usually the Slicestor®appliances) on the bottom of the rack first, and

then work upward.

Unpack and inspect the box and its contents

1. Inspect outside of box for damage.

2. Note if the box was damaged in any way.

3. Open the top of the box and inspect for damage.

4. Remove all of the components from the packaging and inspect for damage.

5. Arrange for assistance when lifting or installing the appliance in a rack. Use a forklift or lift table to

prevent possible injury.

CAUTION: To prevent personal injury and equipment damage, have someone assist you during the equipment installation. If necessary, reduce the weight of the enclosure by removing the hard disk drives and power supply units during installation.

When using the lifting straps, keep them even and at the same level always. Otherwise, the system can slide to one side, and possibly out of the straps completely. Make sure that the rubberized sides of the lifting straps are against the chassis metal.

6. If the appliance itself shows damage, file a damage claim with the carrier who delivered it.

In addition to the appliance, the box includes:

v Rail kits v Cables v Documentation Package

Application installation

Attention: Allow the enclosure assembly to acclimate to room temperature before installation. Store the drives at room temperature for at least 2 hours before use.

Install the handles on the server

You must install two handles on each side of the server before lifting it.

CAUTION: Make sure that you have adequate support to lift the system. Releasing it before it is fixed in the rack might cause personal injury or damage the equipment.

To install the handles on the server, do the following steps.

1. Take out the handle carriers on the rear side by releasing the thumb screws, as shown in the

following figure.

Figure 2. Remove handles from handle carriers

2. Remove all four handles from the two carriers.

3. Install side handles on both sides of server and make sure that they are securely tightened before

lifting the server.

CAUTION: Before lifting or transporting the server, make sure the four side handles (two on each side) are securely screwed into the server. Failure to do so can result in severe personal injury and server damage.

When you are ready to install the server in the rack, you must use a lifting device. Alternatively, use four individuals, each lifting the server by the side handles to place the server in position and begin inserting it into the rack rails.

After the server is partially inserted into the rack rails, you must remove the server side handles to fully insert the server into the rack. Then, you can place the handles back in the drive carriers and replace the carriers into the back of the server.

See "Unlock the rails to insert or remove the chassis" for more details on how to install the server into the rack rails.

If either of the two power supply modules fail, the other module takes the full load and allow the system to continue operation without interruption. However, the global failure indicator on the front panel remains lit until the failed module is replaced.

Each power supply module has three LEDs to indicate power supply status. They are marked with the following abbreviations:

v AC (top LED) v DC (middle LED)

v ! (bottom LED)

The following figure shows the LEDs.

Figure 14. Power supply LEDs

The LEDs are driven by internal circuitry and illuminate in an N+1 configuration even without input power. See the following table for the power supply LED meanings.
